Answer:
5.6 Tesla
Explanation:
L = 52 cm = 0.52 m
V = 2.75 m/s
e = 8 V
Let B be tha magnitude of magnetic field. Use the formula for the motional emf
e = B × V × L
B = e / V L
B = 8 / (2.75 × 0.52)
B = 5.6 Tesla
You'd use the equation kinetic energy=mass*0.5*speed^2
So you'd rearrange this to get mass =kinetic energy /0.5 *speed^2
Which is mass= 1500J/0.5*35^2
=2.44897959183673469........kg
Answer:
Potential
Explanation:
Potential energy is the energy stored while kinetic energy is motional energy.
Potential itself means "having capacity/energy".

For this problem, let's use the approach of dimensional analysis. This technique is done by cancelling out like units that appear both on the numerator and the denominator side. As a result, this technique will let you know that your final answer conforms to what parameter is asked. In this case, the final answer should be in kJ. We use the conversion: 1000 cal = 4.184 kJ The solution is as follows:
<span>6.95×10</span>⁵<span> cal * 4.184 kJ/1000 cal = 2,907.88 kJ</span>
The correct answer D: all of the above
